Great work! Looking good! You haven't had any problems with spruce blanks? Here in Finland we try to avoid pine trees in sauna because it might sweat some resin when warmed. Aspen is the best wood for sauna (at least for benches). Very important thing is the ventilation! Air in in bottom level of stove and out through ceiling.
